Steel storage tanks built to API 650 and its predecessor API 12c (API 653 1.1.1) cover? What does api 653 Minimum requirements for maintaining the integrity of tanks after they have been placed in service and addresses inspection, repair, alteration, relocation and reconstruction (api 653 1.1.1) What does api 653 provide? Tank foundation, bottom shell, structure, roof, attached appurtenances and nozzles to the face of f irst flange, first threaded joint or first welding-end connection (api 653 1.1.2) What is the scope of api 653 limited to? API 653 shall govern for tanks that have been placed into service (api 653 1.1.2) In the case of conflict between api 653 and api 650 or it's predecessor api 12c. Which shall govern? Rules or guidelines to cover all the varied conditions which may occur in an existing tank api 653 1.1.5 API 653 does not contain? The regulations shall govern, however if api 653 is more stringent then api 653 shall govern (api 653 1.3) If any provision of api 653 presents a direct or implied conflict with any statutory regulations, which would govern? API 2015, 2016 and api 2217a Where can you find guidelines to safeguard personnel, prevention of fires, explosions and property damage Except in areas specifically designated as safe for hot work, a hot work permit shall be obtained before starting any work that can involve a source of ignition What does api 2009 state in relation to hot work? API 2009 appendix B Where can you find brief information on inerting tanks? Fitness for service ASNT SNT-TC-1A API RP 2201 API RP 579-1 is? Personnel qualified and certified in NDE? Safe hot tapping practices in petroleum industries is? For design and construction of large, welded low pressure storage tanks Any work on a tank that changes its physical dimensions or configuration accordance with api 653? Standard that was in effect at the date of the installation of the component is the? The AS built standard only for those repairs or alterations API standard 620 is? Define an alteration in The AS built standard The standard used for repairs or alterations made after original construction is? 1. Organisation of the jurisdiction where tank is operated 2. Inspection organisation of the licensed and registered insurance company 3. Owner/Operator Name 3 authorised inspection organisations An employee of an authorised inspection agency who is qualified and certified to perform inspections under API 653 Define authorised inspector A change from previous operating conditions involving different properties of the stored product such as, specific gravity or corrosivity and/or different service conditions of temperature and/or pressure What is a change in service The total metal loss, divided by the period of time over which the metal loss occurred corrosion rate Define What is the tank The portion of the tank bottom or plate within 3" of the inside edge of the shell critical zone? A formal, complete inspection as supervised by an authorised inspector of all accessible internal tank surfaces Define internal inspection 1. Installing a shell penetration larger than 12" beneath the liquid level 2. Installing a bottom penetration within 12" of the shell 3. Removing and replacing or adding a shell plate, exceeding 12" dimension 4. Removing or replacing annular ring material, exceeding 12" 5. Installing a new bottom 6. Jacking a tank shell What does a major alteration or repair include The legal entity having both control of and/or responsibility for the operation and maintenance of an existing storage tank Define owner/operator Work necessary to maintain or restore a tank to a condition suitable for safe operation repair Define When the results of a tank inspection show that a change has occurred from the original physical condition When shall an evaluation be made to determine a tanks suitability for use 1. Internal corrosion 2. External corrosion 3. Stress levels and allowable stress levels 4. Properties of the stored product such as specific gravity, temperature and corrosivity 5. Design temperature and service location 6. External roof live load, wind and seismic loading 7. Tank foundation, soil and settlement conditions 8. Chemical + mechanical analysis of the tank materials 9. Distortion of the existing tank 10. Operating conditions such as, filling/emptying rates What factors should be considered when evaluating a tanks suitability for use When corroded to an average thickness of less than 0.09 inch in any 100 inch squared should roof plates be repaired or replaced All the requirements of API 650 Annex M When What should be considered before changing the service of a tank to operate above 200 F Storage tank engineer Who shall conduct the evaluation of an existing tank shell? Each case must be treated as a unique situation and a thorough inspection conducted to determine the nature and extent of corrosion What must be done prior to developing a repair procedure for shell corrosion The corroded or damaged areas shall be repaired The allowable liquid level of the tank reduced The tank retired satisfied What shall happen if the requirements of API 653 4.3.3 or 4.3.4 can not be Foundation settlement Over or under pressuring High wind Poor shell fabrication Removed What are the causes of shell distortion Cracks in the shell to bottom weld shall be Tanks of welded construction that operate at elevated temperatures (exceeding 200F but less than 500F) Define operation at elevated temperature 30,000 pounds per inch squared When the minimum specified yield strength of the shell material
